How It Works (Formula & Method)
The input is lowercased and trimmed. Every character that is not a letter, digit, space, or hyphen is removed. Runs of spaces and underscores collapse into a single hyphen, and any leading or trailing hyphens are stripped. "Hello World! This Is My Page" becomes hello-world-this-is-my-page.
Worked Example
Below is a worked example using the calculator's default values. The same numbers are pre-filled in the form above so you can press Calculate and see the result without typing anything.
Inputs used:
- Title or Text: Hello World! This Is My Page
With these inputs, the calculator computes the metrics shown in the Results panel. Change any value and press Calculate again to see how the result responds — the live widget and the chart both update instantly.
About the URL Slug Generator
A slug is the human-readable part of a URL that identifies a page — the my-first-post in example.com/blog/my-first-post. Good slugs are lowercase, use hyphens instead of spaces, and contain no punctuation, which keeps URLs clean, shareable, and friendly to search engines.
Tips & Considerations
- Keep slugs short and descriptive — a few meaningful words read better than a full sentence.
- Once a page is published, avoid changing its slug; if you must, set up a redirect so old links keep working.
- This tool strips accented and non-Latin characters. For international content you may want a library that transliterates them instead.
Frequently Asked Questions
Why use hyphens instead of underscores in URLs?
Search engines treat hyphens as word separators but may read underscores as joining words together. Hyphens are the long-standing recommendation for URL slugs.
Should slugs be lowercase?
Yes. URLs can be case-sensitive on some servers, so an all-lowercase slug avoids duplicate-content and broken-link problems.
How long should a slug be?
Short enough to read at a glance — typically three to six words. Trim filler words like "the" and "a" where it still reads naturally.
What does the URL Slug Generator compute?
The URL Slug Generator takes 1 input value and returns 1 result. Turn any title or sentence into a clean, URL-safe slug for blog posts, pages, and permalinks.
